STRIA LITHIUM GRANTS CYGNUS METALS A TWO-YEAR EXTENSION ON PONTAX EARN-IN AGREEMENT

Stria Lithium Inc. has reached a mutual agreement with its partner, Cygnus Metals Ltd., to extend the timeline of the second stage of Cygnus's earn-in agreement on the Pontax lithium project, located in the James Bay region of Quebec.

In July, 2023, Cygnus successfully completed the first stage of the earn-in, acquiring a 51-per-cent interest in Pontax by investing $4-million in exploration expenditures and issuing 9,129,825 fully paid ordinary shares to Stria.

Reflecting the collaborative and constructive relationship between Stria and Cygnus, both parties have agreed to extend the timeline for the second stage of the earn-in by an additional 24 months. This extension provides Cygnus with increased flexibility and a stronger runway to continue its exploration efforts and earn a further 19-per-cent interest, bringing its potential total ownership of the project to 70 per cent.

Under the revised terms, Cygnus will now have until October, 2027, to invest an additional $2-million in exploration activities at Pontax and make a $3-million cash payment to Stria.

As consideration for the extension, and subject to approval from the TSX Venture Exchange, Cygnus will issue 300,000 ordinary shares to Stria at a deemed price of 10.5 Australian cents per share (based on the Australian Securities Exchange closing price on April 1, 2025). These shares will be voluntarily escrowed for a period of 12 months following issuance.

"This extension demonstrates our strong and aligned commitment with Cygnus Metals to unlock the long-term value of the Pontax lithium project," said Dean Hanisch, chief executive officer of Stria Lithium. "We look forward to continued collaboration and to advancing the potential of Pontax as a strategically significant lithium asset in Quebec."

About Stria Lithium Inc.

Stria Lithium is an emerging resource exploration company developing Canadian lithium reserves to meet legislated demand for electric vehicles and their rechargeable lithium-ion batteries. The company is committed to growth through responsible and efficient exploration and development of its mining assets.

Stria's Central Pontax lithium project covers 36 square kilometres, including eight km of strike along the prospective Chambois greenstone belt. The region, known as the Canadian Lithium Triangle, is one of only a few known sources of lithium available for hard rock mining in North America.

Stria's Pontax Central project joint venture with Cygnus Metals now has a maiden Joint Ore Reserves Committee-compliant inferred mineral resource estimate (MRE) of 10.1 Mt (million tonnes) at 1.04 per cent Li2O (lithium oxide) based on the central area of the known mineralization.

This JORC estimate establishes Pontax Central as a significant occurrence in the emerging James Bay lithium region. Cygnus Metals, being an ASX issuer, adhered to Australian JORC Code 2012 guidelines, meaning that such mineral resource estimate is not necessarily compliant with CIM and National Instrument 43-101 standards and the company is not considering them as such at this time.

Cygnus Metals is committed to fully funding and managing the current two-stage exploration and drilling program to a maximum of $10-million at Stria's Pontax property and will also pay Stria up to $6-million in cash. In return, Cygnus may acquire up to a 70-per-cent interest in the property. Cygnus has fulfilled its stage 1 requirements within the agreement and has now earned its 51-per-cent interest in the property.

As momentum builds for the green energy revolution and the shift to electric vehicles, governments in Canada and the United States are aggressively supporting the North American lithium industry, presenting the industry and its investors with a rare, if not unprecedented, opportunity for growth and prosperity well into the next decade and beyond.

Stria is committed to exceeding the industry's environmental, social and governance standards. A critical part of that commitment is forging meaningful, enduring and mutually beneficial relationships with local communities and stakeholders, and engaging openly and respectfully as neighbours and collaborators in this exciting project that has the potential to create lasting jobs and prosperity.
